Audio over LAN and IP audio system with protocols SIP and Peer-To-Peer
Audio over IP: door phone and video door phone, intercom, public address, paging, emergency call pillar.
Audio systems suitable to be used parking lots, schools, railways, airports, subways, hospitals and prisons
ERMES is specially skilled in developing audio communication Over IP with and without video
transmission Over IP of the images. The whole and versatile family of products that ERMES offers to its customers includes hands-free
communication intercoms Over IP, intercoms Over IP with handset, public address and paging Over IP and many other.
All these products use the same software approach that is characterized by then following points:
- hardware and firmware are entirely developed directly from us by our skilled team of engineers that adopt the highest quality standards
(i.e. EN50155 for emergency call and announcement systems installed on boar of trains).
- all apparatuses are IP native and they manage directly the LAN connection without interfaces, adapters or similar devices
- all apparatuses use preferably Peer-To-Peer communication protocols (direct communication between the apparatuses) and consequently
these systems do not require management units, servers or similar main apparatuses: the systems that ERMES offers are "distribute intelligence systems"
and therefore do not exist critical elements that can jeopardize the correct functioning of the entire system.
Nevertheless, when it is necessary, it is possible to adopt apparatuses with SIP protocol
- all apparatuses implement self-testing functions that ensure the continue monitoring of the efficiency of the system
- all apparatuses can be programmed and serviced by remote through the LAN with apposite softwares that use the TCP/IP protocol and therefore you can
make the servicing and the management of the apparatuses by LAN or WAN.
In addition, ERMES produces a range of special equipments over LAN with IP protocol suitable to be used in
in railway, subway and rapid transit field; this range of products includes a surveillance
and emergency call system for coaches that manages the communication inside the train and from train to ground by GSM, an audio/video emergency call system
over LAN for stations, a multifunction emergency communication and evacuation system over LAN for tunnels, a Public Address system over LAN for
AUDIO & VIDEO
The audio door phone over LAN
and the video door phones over LAN that ERMES produces can be connected directly to an
existing LAN and can manage directly the IP protocol. This solution avoid the need to install expensive cable networks reserved to these systems and
consequently let to reduce strongly the installation costs.
Moreover, the use of the static IP address and the Peer-To-Peer protocol let to upgrade the system very easily by adding new equipment or by changing the
addressing of the call without the presence of a SIP server that usually is more expensive and more difficult to set. (
This complete range of intercoms over IP let you to install communication systems without
the need to lay complex and expensive cables network; the intercoms produced by ERMES use the VOIP (Voice Over IP) technology over standard Ethernet LAN in
order to manage the audio communications.
These systems are specially suitable to be used in glassworks, steel mills or other industrial plants as well as in offices, parking areas, public areas
These equipment come with a complete set of functions (selective call, group call, general call, auto-answer, paging and public address mode) that let you
to make simply very complex systems. (more).
PILLAR OVER IP
ERMES produces emergency call equipment over LAN let you to make emergency call systems
suitable to be used in town parks, squares, campuses, stadiums and in all areas where it is necessary to give immediate and effective help.
If you wish to install these energency call systems in motorways or in places where you cannot have the LAN connection in the entire area, you can use
a GSM gateway in order to link the LAN to the remote control room.(more).
& PAGING OVER IP
The transmission of the audio over LAN is a technology that let to make Public Address Systems
in wide areas where the laying of the cables is very expensive.
You can find these problems in shopping plazas, airports, railway stations, seaports, sport facilities, hospitals and in all wide dimension areas with
presence of many people.
In addition, the high quality of the audio transmitted let to make music diffusion systems in hotels, commercial centers and similar facilities.

Ultimately, ERMES produces a family of audio over LAN equipment that uses the audio over IP and the VoIP (Voice over IP)technology in
order to transfer audio, video and data. These equipment let you to install easily and inexpensively IP intercom systems, IP emergency call systems,
public address and paging systems, audio and video entry door systems over a LAN by using on ly the LAN without additional cables.
You can use these IP audio and IP video equipment under the sole condition that a LAN network is available: you can install highly reliable intercoms,
emergency call and public address systems. In fact the intercoms, the emergency call systems, the public address systems produced by ERMES do not require
dedicated LAN: these equipment can use the existing LAN and can work jointly with previously installed systems.
Ermes let you to solve in reliable and cheaper way the problems involved in the installation of the following systems:
- Audio entry systems Over IP and video entry systems Over IP
- Industrial Intercom Systems Over IP
- Emergency call pillars Over IP and emergency call boxes Over IP for public areas, sport/athletic facilities,
public parks, hifgways,railway stations and similar
- Public address systems Over IP and paging systema Over IP
